FASTENING AND SEATING 0F GUARD-RAILS, 810., FOR STREET-RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 472,165, dated April 5,1892.

Application filed July 15, 1891.

To all whom it may concern.-

Be it known that I, JOHNA.DUGGAN,a citizen of the United States,residing at Quincy, in the county of Norfolk and State of Massachusetts,have invented certain new and useful Improvements in Fastenings andSeatings of Guard-Rails and other Rails for Street-Railways; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in fastenings and seatings ofguard-rails and other rails for street-railways; and the object of myimprovement is a chair adapted to receive both the main and guard rail,with means for firmly securing .the rails thereto,- thus avoiding thenecessity of using special rolled guard-rails and enabling builders ofstreetrailways to construct guard-rails by the use of the ordinary T orgirder rails by bending said rails to the curves required and securingthem in proper position by the said chair and fastenings.

In the accompanying drawingslhave shown in Figure 1 arailroad-track onacurve; in Fig. 2, a section through main and guard rail, showing thechair on which both are seated; in Fig. 3, a side View of the rails andchair; in Fig. 4, a plan view of the chair, the rails being removed; inFigs. 5 and 6, a detail of the clamp, and in Fig. 7 a section showingsubstantially the same chair and fastenings applied to a different shapeof guard-rail.

A A A are the railroad-ties; B B, themain or running rails, and O theguard-rail placed as usual, being always higher than the running-rail,in order better to guide the flange of the wheel WV, as shown in Fig. 2.

D is the chair, made of cast-iron or other suitable material, spiked toties in the customary manner. The top or seating surface of this chairis adapted to the different heights of the guard and running rail, asshown in Figs. 2 and 7.

The chair D is provided with ear-shaped clamps E E, fitting over theside pieces h h of the chair. Clamp E is an improvement on thatdescribed in the application for Letters Patent filed by me October3,1890, Serial No.

Serial No. 399,620. (No model.)

367,124. This improvement consists in providing the clamp with a rib g,placed at the narrow end of the clamp. This rib serves the threefoldpurpose of making the clamp stronger, of covering a larger space on thelower flange of the rail, so that the same chair and clamps will workfor rails of different Widths of flange, and of offering a largerprojection beyond the side pieces 71 h to strike and hit with the hammerin driving the clamp to its proper position.

In thus constructing my clamps it becomes necessary to make a right-handand a lefthand clamp for each chair, the flange being always at thenarrow end of the clamp-that is, at that end to which the hammer isapplied in driving the clamp onto the chair. The end opposite to the ribg is chamfered slightly on the inside, so that it may be placed readilyin position without liability to catch or bind.

This construction is shown in Fig. 5. The inside lower line (shown as 12 in Figs. 5 and 6) is made tapering, so as to conform to the taperingline of the corresponding part of the side pieces h h on the chair D, asshown in Fig. 3. The filling-blocks b and bolts asecure the running-railB and guard-rail C in their proper distance from each other and preventspreading apart. As the tendency of the wheels of a moving car is topush the guard rail 0 toward the center of the track, I provide on mychair a brace f, which fits against the center web and up under the headof the rail. This brace'carries any lateral strain on the head of therail directly to the base of the chair and relieves the clamp oppositeto the brace from any undue strain, which in the event of a very high(or deep) rail and a very low chair would be severe.

What I claim, and desire to secure by Lettel-s Patent, is-

1. The combination of the main rail 13, the guard-rail 0, both seated onthe chair D, and the clamps E, bearing upon the upper and outer surfaceof the rail-flange, substantially as and for the purpose abovedescribed.

2. The combination of the main rail 13, guardrail 0, filling-block b,rails 13 and 0 being seated on the chair D, and clamps E, bearing uponthe upper surface of the rail-flanges, substantially as and for thepurpose above described.
